Description

Outsole for Degenerative Osteoarthritis of Knee Joint and Shoes Therefor}

The present invention relates to a sole for a degenerative knee and a shoe having the same. More specifically, an abnormal lower limb skeletal alignment is corrected while the foot slides inward or outward by an inclined surface formed on the support member, and shock absorption is performed by the shock absorbing member. And soles for degenerative knees to improve resilience and shoes having the same.

The knee joint is a part that balances the weight of the body that the human body should support with four feet so that it can stand without falling down. Therefore, the knee joint is moving little by little to balance the body even when we are not aware of it.

At this time, most ideally, the center of the weight should pass through the center of the knee joint, but most people do not pass the center of the knee joint, so large loads continue to act as part of the knee joint. Because of this, the knee joint is one of the areas where the degenerative change occurs with age. In addition, incorrect walking habits result in abnormal lower extremity skeletal alignment, which causes large loads to continue to act as part of the knee joint.

Degenerative knee osteoarthritis may cause symptoms such as knee pain when standing up, trembling knees when standing, sound when bending or spreading knees, or gaping between one or more fists in a standing position. . In addition, it is a disease that can be suspected when symptoms such as pain is particularly severe when going down the stairs, or pain that occurs after walking for more than two days to three days.

The goal of treating arthritis is to reduce pain and increase joint flexibility. Most arthritis cannot be cured. For milder symptoms, pain and stiffness can be alleviated with constant physical therapy, medication, or weight loss. However, patients with severe arthritis can reduce pain through surgery or restore joint function through reconstruction. However, these surgeries are often expensive and cumbersome and can't be done.

1 is a front view showing the right lower limb alignment of the "O" shaped knee, and FIG. 2 is a front view showing the right lower limb alignment of the "X" shaped knee. As shown in FIGS. 1 and 2, in the lower limb alignment (1) of a person with an "O" shaped knee and the lower limb alignment (9) of a person with an "X" shaped knee, the mechanical axis 50 is the femoral head center. (3) shows a line connecting the center of the head (5), the bending axis 70 means a line connecting the center of the femoral head (3) and the center of the knee joint (7).

Genu Varum, commonly referred to as an "O" shaped knee, is an "O" shaped knee that does not stick to each other when the legs are brought together when the bending axis 70 is inclined out of the mechanical axis 50. Refers to legs bent in shape. Genu Valgum, which is referred to as an "X" knee, refers to a leg that is bent out of the knee joint when standing with both legs together when the bending axis 70 is inclined inward of the mechanical axis 50. The larger the value of the inclination angle β between the bending axis 70 and the mechanical axis 50, the more severe the "O" -shaped knee and the "X" -shaped knee.

Abnormal lower extremity skeletal alignment, such as "O" and "X" knees, may be caused by congenital or acquired factors, resulting in degenerative knee arthritis or wear-out of the knee joint because the load is concentrated in one part of the knee joint. Happens.

In order to alleviate and prevent the pain of degenerative knee arthritis and to correct abnormal lower limb skeletal alignment, shoes are formed so that the foot is inclined inward during walking. These shoes form a shoe that includes a sole and an upper formed so that the foot is inclined to the inside of the shoe, and when the user walks on the ground while wearing the shoe, the foot and the legs themselves are inclined to the inside of the shoe, and the knees move inwardly. Induced methods were to correct abnormal lower limb skeletal alignment or treat degenerative knee arthritis.
